Abstract

A mirror mount is disclosed that can independently rotate a mirror around two orthogonal axes in the plane of the mirror. This mirror has the same degree of freedom of motion as a mirror which pivots around a single point in its plane.

Gimbal Mounted Mirror

      A mirror mount is disclosed that can independently rotate a
mirror around two orthogonal axes in the plane of the mirror.  This
mirror has the same degree of freedom of motion as a mirror which
pivots around a single point in its plane.

      Such a mirror drive can be implemented with two sets of pivots,
positioned on orthogonal diameters in the plane of the mirror.  Each
set of pivots is linked to a horseshoe shaped fork, the forks are
permitted to rotate around their axes.  The axes of the forks may be
in the same plane or they may be offset to each other (Hooke's
joint).  See sketch.

      The mirror can be positioned to any angle by driving the two
forks.  In a modification to the basic design, one of the forks may
be only "half a fork", being linked to the mirror at only one pivot
point.
